Rare Earth Separation's Hidden Chemical Trap: China Controls More Than the Minerals

Highlights

• Hydrochloric acid costs roughly $27/t in China versus $162/t in the U.S., a sixfold gap that compounds rare earth processing cost disadvantages.
• Specialty organophosphorus extractants like P204 and P507 are strategic chokepoints where Chinese manufacturing competes with Western-branded but globally sourced products.
• The 2026 Middle East conflict pushed U.S. Gulf sulfuric acid prices to ~$400/t, illustrating how chemical supply shocks can cripple rare earth processors regardless of ore access.
• U.S. policy should prioritize domestic production of critical extractants, reagent recovery systems, and strategic chemical inventories rather than duplicating China's entire commodity chemical industry.
